, IMPROVEMENT IN COTTON-GINS.

Specification forming part of Letters Patent No. 15,930, datedOctober 21, 1856.

50 all whom it may concern:

Be it known that I, JAMES B. MELL, of Riceborough, in the county of Liberty and the State of Georgia, have invented a new and useful Machine for Ginning Black-Seed or Sea- Island Cotton; and I do hereby declare the following is a full and exact description thereof, reference being had to the accompanying drawings numbered 1 and 2, and to theletters of reference marked thereon, and which are made part of this specification.

Figurel is a longitudinal cross-section. Fig. 2 is a partial side elevation.

The nature of my invention consists in the arrangement of two or more sets of ginningrollers in an arch of the cleaning-cylinder, in combination with brushes so arranged as to keep the rollers clean, and the fan F, for removing the cotton from them as fast as ginned, substantially as is hereinafter described. a

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation by reference to Figs. 1 and 2 annexed to this specification, with the letters marked thereon.

In Fig. l, A is a frame of cast-iron, with a front of perforated tin from R to R, and a slatted bottom. Within this frame is a re-' volving feed-roller, B, the end of which is of cast-iron. The periphery is covered with gauze-wire, and along the face of this periphery are bars which hold the teeth G, as

shown in Fig. 1. The shaft of roller B is a' cleanse the cotton from dirt before it reaches the rollers O O. Mis a semicircular slot, having its concave face presented to and corresponding with the convex face of roller D, and so arranged that rollers G G are fixed therein, presenting in combination a concave face to roller B. Rollers O G G C are gin rollers of equal size in any one machine; but the length and size may be determined in each gin by the material used and the size of the gin desired, and the number used in any gin may be increased, as hereinafter described. These rollers may be of wood or metal, and

should be slightly grooved. D D are confining friction -rollers; E, the fan worked. in roller B, and above described; F, a fan placed outside of the slot M, and near the lower end of rollers O G G O, and working in a direction reversed to the descending cotton,anddesigned fully to separate the dirt from the cotton and drive the cleaned cotton along the line 0 O to the place of discharge. signedtopreventthecottonfromwindinground the rollers after it has once passed through them; I, the frame of the friction-bend; K, the friction-bend; L L, friction-rollers; M, slot in which rollers O G G 0 work, being the same radius as feed-roller B; N, aperture for the introduction of cotton; 0 O, a perforated metallic plate or an apron of gauze-wire extended from slot M on an inclined plane to an aperture for discharging the cleaned cotton 'at the back of the frame A; B R, sheets of perforated tin. i

In Fig. 2, A is a section of frame; B, slot; 0, frame of friction-bend; D D, cog-pinions; E, movable frame confining rollers; F, pivot on which frame works. Rollers O G G G are moved by cog-wheels on each side of the slot, and so arranged that each roller works ina direction the reverse of the one adjacent to it, but all with equal velocity. The length of semicircular slot M may be increased in each machine, so as to extend to the vertical point of roller B; or the size of roller B may be increased. In either case'the number of rollers in the machine may be increased, thus increasing the amount of work done by the machine in a given time.

Operation: The cotton to be ginned is slightly shaken by hand into aperture Nat the top of the gin, when it is carried round by the teeth G of feed-roller B to the gin-rollers O C O C. It may, at the pleasure of the operator, be carried round in either direction by reversing the motion of the roller B and the position of rollers G. The cotton is slightly opened by teeth G. The blast. of fan E, which revolves rapidly, blows the dirt out of the cotton, and also blows the dirt, and seed, after they are separated from the cotton, out of the perforated front B R and the slatted portion. The cotton brought by teeth G to rollers O O O O is drawn through the grooves of these rollers, and is separated from the seed. The

H H are brushes dea brushes H prevent the cotton from. Winding fan F and driven out of aperture at the end ofOO.

WVhether the arrangement of fan E within roller 13, as described above, be new and be my invention, I do not claim it in these Let ters Patent, nor do I waive my right to it in another patent; but

That I claim as my invention is The arrangement of two or more sets of ginning-rollers in an arch of the radius of the cleaning-cylinder, in combination with brushes so arranged as to keep the rollers clean, and the fan F, for removing the cotton from them as fast as ginnod, substantially as hereinbefore described.
